Hi everyone. I live in an area with lots of feral cats, recently one has taken to me which was very pregnant, she had her kittens in my shed and I brought them inside into the spare room (no humans) so I could keep them warm and make sure mum was properly fed. Mum doing really well as are all the kittens, but one kittens tail is 4X shorter than the others. Is this something to be concerned about? Photo attached
